John XXIII’s prayer for peace

Lord Jesus Christ, who are called the Prince of Peace, who are yourself our peace and reconciliation, who so often said, “Peace to you,” — grant us peace. Make all men and women witnesses of truth, justice, and brotherly love. Banish from their hearts whatever might endanger peace. Enlighten our rulers that they may guarantee and defend the great gift of peace. May all peoples of the earth become as brothers and sisters. May longed-for peace blossom forth and reign always over us all.
